IGP disabled and display set to PEG are the default settings now. Run DDU/third option (safe mode)

Enable 'F8' boot option.

cmd (Admin)

bcdedit /set {default} bootmenupolicy legacy

F8 -> safe mode -> DDU clean & shutdown

F8 -> "Disable Driver Signature Enforcement"

Install v344.80 http://forum.techinferno.com/nvidia/6307-%5Balienware%5D-aftermarket-upgrades-driver-support-modded-inf-9.html#post114229

did exactly as you said, but still mid instal the screen just turns off

As I said, you need to disable driver signing first.

yeah I did that, tried it again just to be sure, and got the same result :/

• Win8 -> Disable driver signing.
  
• Download Geforce 344.80 Beta
  
• Extract driver with 7-Zip -> Extract to "344.80-notebook-win8-win7-64bit-international-whql"
  
• Display.Driver folder -> copy/overwrite nvdmi.inf (unzip).
  
• Extracted driver folder -> run setup.exe
  Safe to delete. My driver folder.

,

ok did that , but got blackscreen while installing driver , rebooted a bit later and still got an blackscreen as soon as windows finished booting :/ i went a bit thru the post and shall i repeat the progress with remounting the card?

Ok used DDU to remove the driver, extracted the new one and deleted Display.NView Display.Update and Display.Optimus, but could´nt find NVWMI , copy/pasted nvdmi and startet setup , but failed to install :/

Thanks for the quick answer,

caused two new ones, the first with the posts , just five posts , excluding spamming of course , or the membership what i prefer atm , because im not that into forums, mainly because im not that confident in writing english.

and the second one , i just have to repeat the progress with the driver you are refering to and remove the other one i installed?

Hey J95,

I hope you can help me out, I upgraded my m17x r3 (win8.1) with a 680m and modded the 344.75 driver, disabled the driver signing via cmd and installed the driver ( was asked if I want to install it, pressed yes) then rebooted and got a blackscreen.

So I disabled the IGP and set display to PEG, and now I am here.

Device manager displays my GPU as Microsoft Basic Display Adapter and the id changed.
